Radiofrequency Catheter Ablation Of Atrioventricular Nodal Reentrant Tachycardia Associated With Anomalous Drainage Of Both Superior Vena Cava Into Coronary Sinus

Indian Pacing and Electrophysiology Journal, 2009
Total upper body drainage via left superior vena cava into coronary sinus (i.e. absent right superior vena cava) is a rare anomaly and distorts the anatomy of coronary sinus and triangle of Koch.

Sinus arrest in a patient with acute coronary syndrome due to a rare anatomical variation in the sinoatrial nodal artery

BMC Cardiovascular Disorders
Background Sinus node dysfunction can occur in patients with acute coronary syndrome (ACS), particularly in inferior myocardial infarction. Because the sinoatrial nodal artery (SANa) shows considerable anatomical variation, ischemia-related sinus arrest ...

Effect of Bileaflet Valve Orientation on the 3D Flow Dynamics in the Sinus of Valsalva

Journal of Biomechanical Science and Engineering, 2011
Three-dimensional (3D) evolutional behavior of flow dynamics in the aortic sinus of Valsalva was studied in vitro for finding the effects of bileaflet valve orientations in an effort to investigate possible linkages between the sinus flow and coronary ...

Giant coronary sinus aneurysm secondary to right coronary arteriovenous fistula leading to pseudo-mitral stenosis. [PDF]

, 2011
We herein report a case in which a right coronary to coronary sinus arteriovenous fistula determined progressive aneurysmatic dilatation of the coronary sinus. Severe compression of the left atrium ensued.

Validation of an Automated Artificial Intelligence‐Driven Planner for Transcatheter Aortic Valve Replacement

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Preprocedural planning with multislice computed tomography (MSCT) is an essential prerequisite for successful transcatheter aortic valve replacement (TAVR). However, preprocedural planning is time‐consuming and may contain clinically meaningful interobserver variability.

Anatomy of coronary sinus ostium

Folia Morphologica, 2016
The coronary sinus is the main cardiac vein and it has become a clinically important structure especially through its role in providing access for different cardiac procedures.The study was carried out on 100 randomly selected adult human cadaver hearts fixed in 10% formalin.

THE RELATIONSHIP BETWEEN THE DEFAULT MODE RESTING STATE NEURAL NETWORK, RESPIRATORY SINUS ARRHYTHMIA, AND SELF-FOCUSED COGNITION: AN EMPIRICAL ANALYSIS [PDF]

, 2013
Functional activity within the default mode resting state neural network (RSNN) and the resting respiratory sinus arrhythmia (RSA) may represent an integrated neural and peripheral cardiovascular index of the baseline, resting state in humans.

Coronary Perforation During Excimer Laser Angioplasty in a Patient With Prior Thoracic Radiotherapy

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Management of heavily calcified coronary lesions remains challenging despite advances in plaque‐modifying technologies. Excimer laser coronary angioplasty (ELCA) is an effective adjunctive strategy with a low risk of no‐reflow. Case Summary A 75‐year‐old woman with non–ST‐segment elevation acute coronary syndrome and severe left ...

Idiopathic Coronary Sinus Thrombosis

JACC: Case Reports
A 62-year-old man with acute coronary syndrome underwent an echocardiogram for evaluation. A transthoracic echocardiogram revealed masses within a giant coronary sinus. This case highlights the role of multimodality imaging in investigating coronary sinus enlargement, coronary sinus thrombosis, and the approach to management.
